Procedure

A solution of diethyl-{4-[3-((S)-3-ethyl-5-methyl-4-oxiranylmethoxy-phenyl)-[1,2,4]oxadiazol-5-yl]-6-methyl-pyridin-2-yl}-amine (100 mg, 0.229 mmol) in 5.4 M NaOMe in methanol (5 mL) is stirred at 70° C. for 72 h. The mixture is diluted with EA and washed with water and brine. The org. extract is dried over Na2SO4, filtered and concentrated. The crude product is purified on prep. TLC plates with heptane:EA 1:1 to give the title compound (91 mg) as a yellow solid; LC-MS*: tR=1.21 min, [M+1]+=455.09; 1H NMR (CDCl3): δ 1.25 (t, J=7.0 Hz, 6H), 1.33 (t, J=7.5 Hz, 3H), 2.41 (s, 3H), 2.50 (s, 3H), 2.58 (d, J=5.0 Hz, 1H), 2.77 (q, J=7.8 Hz, 2H), 3.47 (s, 3H), 3.59-3.70 (m, 6H), 3.92 (d, J=5.3 Hz, 2H), 4.19-4.27 (m, 1H), 7.01 (s, 1H), 7.10 (s, 1H), 7.87 (s, 1H), 7.88 (s, 1H).
